¹There is a problem of
translation here with regard to the word Oriental
(essential for national identification:
question: ¿nacionalidad? answer:
oriental). República
Oriental del Uruguay, for example,
literally means Republic East of the Uruguay, but it is
also often translated as Oriental Republic of Uruguay.

Territorial Disputes: In 2010, the
ICJ ruled in favor of Uruguay's operation of two paper
mills on the Uruguay River, which forms the border with
Argentina; the two countries formed a joint pollution
monitoring regime; uncontested boundary dispute between
Brazil and Uruguay over Braziliera/Brasiliera Island in
the Quarai/Cuareim River leaves the tripoint with
Argentina in question; smuggling of firearms and
narcotics continues to be an issue along the
Uruguay-Brazil border.
